Rheological behavior of amylopectin and beta-lactoglobulin phase-segregated aqueous system

Quiroga, Carmen Carla and Bergenståhl, Björn LU (2008) In Carbohydrate Polymers 74(3). p.358-365
Abstract
The rheological behavior of amylopectin-beta-lactoglobulin-water system in the region of incompatibility was studied by performing constant shear rate and oscillatory measurements. Phase-segregated samples were prepared at concentrations that laid over the binodal and tie-lines. The results were interpreted in terms of the isostress and isostrain blending laws. For this purpose the bases of Takayanagi model was used and a modified model considering the gradual formation of double emulsions close to the phase-inversion concentration that explain the transition was proposed. Good agreement between observed and calculated values was obtained using the isostress and isostrain models. Phase segregation and the phase-inversion control the... (More)
